"Thirty spokes will converge in the hub of a wheel;
but the use of the cart,
will depend on the part of the hub that is void.
With a wall all around a clay bowl is molded;
but the use of the bowl,

Cut out the windows and doors in the House
as you build; but the use of the House,
will depend on the space of the walls that is void.
So advantage is had, from whatever is there;
but usefulness rises, from whatever is not."
